Intel made an enemy out of Apple back in 2010 when it helped create the so-called "UltraBook," which was powered by Windows but looked an awful lot like the MacBook Air. Partly in response, Apple started making its own A-series chips (with more than a little help from frenemy Samsung), and now the chip giant is reportedly paying for its "backstabbing style of partnership." According to an extensive report, Intel's move has cost it around $7 billion in losses.
